Improvement in alarm-locks



@nicht @i O. D. WARNER,.OF BRISTOL, CONNECTICUT, ASSIGNOR TO HIMSELF ANDS. M. SUTLIFF, CETHE- SAME PLACE.

Letters Patent No. 86,116, dated January 19, 1869.

To all whom it uta/y concern: l

Be it known that I, O. D. WARNER, of Bristol, in the county of Hartford,State of Connecticut, have invented a new and improved Alarm-Lock andLatch; and I do hereby declare that the following is a full, clearLandexact description thereof', which will enable others skilled in the artto make and use the same, reference being had to the accompanyingdrawings, making a part of this specication, in which- Figure 1 is afront elevation of my invention.

Figure 2 is a side elevation of the bell, attached to the cap or plate.

Figure 3 is a side elevation of the hammer, for sounding the bell.

Similar letters of reference indicate like parts.

My inventioneonsists in placing between or near a latch-bolt andlockfbolt a bell, and a hammer for.

sounding the same, which hammer is operated by the slidingof eitherbolt.

A designates the latch-bolt, and B, the lock-bolt, both -of which areconstructed in any proper manner, and are the same as many in commonuse.

C designates the bell, attached tothe inside-of cap or plate D.

E designates a sliding hammer, for sounding the bell C, and having itsbearings in stu'ds a @and placed parallel with the bolts A and B.

At each side of hammer E, I place a stud, b, the top of which isinclined with the highest point from the bell C, and higher than theelevations d d on the topf of hammer E.4 The sides of elevations d dnearest the bell C are at or nearly at right angles with hammer E, whiletheir opposite sides are bevelled or inclined. clined. v 'Io the bolts Aand B, I firmly attach, in any proper manner, a spring-bar, F.

When the bolts 'A or B are extended outward, the spring-bar F rests on'the'hammervE in front of elevations cZ rl. As the bolts A or B arecaused to slide nward, the spring-bar F strikes elevation d, and slidesthe hammer E with 'it until the inclined stud b raises the spring-bar Fover the elevation d, and the hammer E is released and driven againstthe bell C by the spring G, while' the smaller and weaker spring c willdraw the hammer E back sufciently to give the bell C a clear tone. Asthe bolts A or B extend outward again, the `spring-bar F slides up thebevelled side `of and over elevation d into its former position. i 4

I place, in the inside ofthe box or frame H of the lock, a slidingwedge, enwhich is held in ,a slot, not shown, and provided with a stud,fitted in said slot, by which it can be operated from the outside of thelock. By sliding the wedge e firmly between the ame'H of the'lock andthe bell C, it will prevent the ringing of the bell C, and its sound,when struck by the hammer E, will be only a click. v

This lock and latch is designed for. the ordinary mortiselock and latch,with the bell C inside; but, if 'desired, the spring-bar'F could be seton the side of the bolt, instead of its front, and extend through thelock to the inside side of the door, and the bell C, with the hammer Eat e, in proper position under it, placed on the inside side of thedoor.

The ordinary latclnknob cbuld be labelled, bell, and attached to thislatch, when it would answer for a call-bell, while it will always answerfor an alarm, to inform when either the lock or latch is turned.

If desired, the hammer E and bell C can be used for a door-bell, withoutcombining them with a latch or lock, by simply providing any slidingbolt, to attach the spring-bar F, for operating the hammer.

Alarm-bells have before been combined with locks, with a smallmechanical movement, so arranged that, by winding and setting, thelock-bolt would, when moved, set the movement in motion, which wouldoscillate a hammer, and sound the bell; but such or similar combinationsI do not claim; but

What I claim as new, and desire to secure by Letters Patent, isv l. Thecombination and arrangement of the frame H, sliding wedge'e, bell C, andhammer E, operating substantially as and for the purpose described.

2. The combination of bolt A or B, spring-bar F, hammer E, with itselevations d d, inclined stud b, springs G and c, and bell C,substantially as and for the purpose desclibed. v

O. D. WARNER.
